Drywall rasp

Abstract

A rasp tool for smoothing the rough edges of cut drywall and the like including an elongated housing which is substantially U-shaped in cross-section and which defines a pair of legs disposed spaced relative to one another with each leg defining a distal end. A pair of slots extend along the inside surface of each of the legs longitudinally relative to the housing and parallel relative to each other. The housing further supports a rasp blade with the edges of the blade removably received in the pair of slots such that the blade is spaced from the distal ends of the legs so as to define slide guides on the inside surface of each of the legs.

I claim: 
     
       1. A rasp tool for smoothing rough edges of cut drywall, said rasp tool comprising: an elongated housing which defines an arcuate outer surface and a pair of rounded edges and which is substantially U-shaped in cross-section and which defines a pair of legs disposed spaced relative to one another with each leg defining a distal end and an inside surface;   a pair of slots defining opposed upper and lower spaced surfaces extending along said inside surface of each of said legs longitudinally relative to said housing and parallel relative to each other; and   a rasp blade having a pair of edges which are removably received in said housing by sliding said edges into said pair of slots between said upper and lower spaced surfaces in a direction parallel to the longitudinal axis of said housing and such that said blade is spaced from the distal end of said legs so as to define slide guides on said inside surface of each of said legs, said rasp blade being held against movement in a direction perpendicular to the plane of said rasp blade by said opposed upper and lower spaced surfaces of said pair of slots.   
     
     
       2. A rasp tool as set forth in claim 1 wherein said slide guides extend substantially the length of said housing between said blade and said distal ends of said legs on said inside surface of each of said legs. 
     
     
       3. A rasp tool as set forth in claim 1 wherein said pair of slots lie in a common plane which is spaced relative to said distal ends of said legs. 
     
     
       4. A rasp tool as set forth in claim 1 wherein said pair of legs are disposed in spaced parallel relationship relative to one another. 
     
     
       5. A rasp tool as set forth in claim 4 wherein said legs are spaced apart a sufficient distance to accommodate 1/2 to 5/8 inch thick drywall sheets. 
     
     
       6. A rasp tool as set forth in claim 1 wherein said U-shaped housing defines an arcuate outer surface and a concave wall disposed opposite said outer surface. 
     
     
       7. A rasp tool as set forth in claim 1 wherein said housing is made of molded plastic. 
     
     
       8. A rasp tool as set forth in claim 1 wherein said housing is made of metal.
